Cardiovascular System
Cardiovascular System Cardio = “heart” Vascular = “vessels”
Cardiovascular System Cardio = “heart” Vascular = “vessels” Made up of heart, vessels, and blood
Cardiovascular System Cardio = “heart” Vascular = “vessels” Made up of heart, vessels, and blood Closed system—blood stays inside the vessels
Cardiovascular System Cardio = “heart” Vascular = “vessels” Made up of heart, vessels, and blood Closed system—blood stays inside the vessels Blood only flows one-way
What is another name for the cardiovascular system? Respiratory system Circulatory system Immune system Skeletal system 9 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30
Types of Blood Vessels Arteries—move blood away from the heart
Types of Blood Vessels Arteries—move blood away from the heart Veins—move blood toward the heart

What parts of the blood help fight off disease and heal injuries? white blood cells & platelets red blood cells & platelets white blood cells & red blood cells white blood cells & plasma 9 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30
Which is not a function of the cardiovascular system? Carry nutrients & oxygen to body cells Carry carbon dioxide & waste away from body cells Attack disease-causing bacteria Produce chemicals that control body processes 8 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30
